The Quick Read: Your limit is the smallest of three numbers: value times the combined leverage cap minus every lien already on the rental, the program’s line-size band, and the rent coverage test. On a second lien the cap is typically 70% combined loan-to-value (CLTV) at a 720 score or better, on lines of $50,000 to $500,000, subject to underwriting.
- A second lien sits behind the first mortgage you keep. A first lien exists only on a rental with no mortgage.
- Rent must cover a stress payment on the entire line, typically at 1.10x or better, drawn or not.
- First-lien leverage runs 75%, 70% or 65% depending on score and line size.
- The line draws against one rental’s equity and gives you cash for the next deal. It does not close with the purchase.
You hear “DSCR HELOC” and picture a giant pool of equity across your portfolio. It is narrower than that. Here is how the sizing works, where the limits bind, and how the cash turns into a down payment.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a revolving line of credit secured by a rental you own. DSCR stands for debt service coverage ratio, which is monthly rent divided by the qualifying payment. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. That means no traditional personal-income documentation, W-2s or personal income calculation.
The label is not standardized across the market. Some products sold under the name are closed-end seconds that pay out one fixed amount. The program described here is a true line of credit, placed through select programs in Lendmire’s wholesale network.
For the general mechanics of a home equity line, the CFPB explains that a HELOC is an open-end line that lets you borrow repeatedly against equity, and that equity is home value minus what you owe. That definition fits here. The qualifying method is what differs: this line looks at the rent, not your paycheck.
Two structures exist:
- Standalone second lien. You keep your first mortgage. The new line sits behind it.
- Standalone first lien. The rental has no mortgage, so the line is the only loan on it.
It is never a third lien, and it is never closed together with a purchase. It is also never a line on your own home or a second home. The LLC can stay on title, subject to program terms, with members signing as guarantors.
How Much Can You Borrow? The Formula
The formula is simple. Take the appraised value, multiply by the CLTV cap, then subtract every lien already on the property. What is left is the most the equity allows.
Use appraised value, not what you paid. An old second mortgage or an unreleased line reduces the room, so find those first.
Here is a worked picture, using percentages only. Say a rental is worth $400,000 and the first mortgage sits at 40% of value. A second lien at a 70% CLTV cap leaves 30% of value as room. If the first mortgage sits at 60% of value, only 10% of value is left. And at 70% there is no second-lien room at all.
Notice what happened. The same property supports a large line or none, depending only on what you already owe. Lenders count the first mortgage against you because the test is combined. Rising value helps. Paying down the first mortgage helps. Wishing does not.
Second Lien vs. First Lien: What the Tiers Say
The lien position sets your leverage cap. Across the programs we place files with, the structure looks like this, subject to underwriting:
| Lien position | Score | Leverage cap | Line size |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000 to $500,000 |
| Second lien | Below 720 | No option | None |
| First lien (no mortgage) | 740 or better | 75% LTV | Up to $500,000 |
| First lien (no mortgage) | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien (no mortgage) | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
Two points matter here. First, a borrower who keeps a first mortgage can only take a second lien, so a 700 to 719 score with a mortgage in place has no cell in the grid. Second, anything above $500,000 is a first-lien line only, and it carries the 65% ceiling.
Some programs also flag declining markets and lower the ceiling by 5 points. These are ceilings, not offers.
Market surveys paint a different picture for bank lines. Yahoo Finance reports that investment-property HELOCs from conventional lenders often run 75% to 80% LTV with credit in the 700 to 720 range, and that these tests lean on personal income. For this program, the network figures above govern, not those survey numbers.
When Does the Line-Size Cap Bind Before Leverage?
It binds at both ends. Lines start at $50,000, so a small equity cushion can fall below the minimum. A rental with only a sliver of room under the 70% cap may not support even the smallest line.
At the top, a second lien stops at $500,000 no matter how much equity you hold. Picture a rental with enough equity for a larger line but a first mortgage you want to keep. The second-lien ceiling holds the line at $500,000. Only a mortgage-free rental can go higher, up to $1,000,000, and then at the 65% ceiling.
Rent coverage is the third gate.
How the Rent Coverage Test Sizes the Line
The line must clear a minimum 1.10x coverage ratio. The qualifying payment is a fully amortizing principal-and-interest payment on the entire credit limit, calculated at the start rate plus 2 percentage points. That is a stress payment. Taxes and insurance are not part of it.
The key detail: the stress payment applies to the full limit, whether you draw it or not. A line you size too big can fail the coverage test even if you plan to use half of it. Asking for less can fix a failing file.
Rent is the lesser of the appraisal’s market rent (Form 1007) and the lease, unless three months of receipts support a lease above market. A lease in place is required. A two-to-four-unit property may have at most one vacant unit.
How the lender treats the first-mortgage payment on a second lien is a point to confirm on your file. The lender’s own coverage calculation governs, and the arithmetic here is illustrative only.
A bigger line raises the stress payment and lowers coverage. So a rental with thin rent can hit the coverage wall before it hits the leverage cap.
How Does the Draw Work?
At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, that means the whole line comes out at closing. Later draws must be at least $5,000 each.
This makes the product behave less like a standby line than a bank HELOC. You do not park a big unused limit and dip in occasionally. You size the line to the cash you need now.
The draw period runs 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period begins, for a 30-year maturity. The rate is variable.
Payment shock is the risk to plan around. The CFPB notes that payments can rise significantly once repayment begins. Experian describes the draw period as the stretch when you typically pay only interest, followed by repayment with no more draws. Plan an exit, such as refinancing the newly bought property, before the interest-only years end.
Can the Line Fund a Purchase Directly?
No. The line never closes with a purchase. It pays out against the rental you already own, and you take that cash to the next deal as a down payment or as capital for a renovation.
The order runs like this:
1. Confirm the source rental has cleared both seasoning clocks.
2. Close the line on that rental and take the closing draw.
3. Hold the cash and line up financing on the new property.
4. Buy the new property with its own loan, often a DSCR purchase loan.
Equity in rental A cannot be borrowed against rental B. Each line attaches to one property. If you have no rental with equity, this tool is not your first step.
One caution on the purchase side. The new property’s lender reviews where your down payment came from, so expect to document the line.
Seasoning: The Waiting Rule
A rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date). That is the full rule. A recent purchase has to age before it can back a line.
What Does the File Need?
Valuation depends on line size. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better plus a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted.
Credit sets your tier, using the lender’s own report. There can be no 30-day mortgage late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale or deed in lieu. No reserves and no cash to close are required. Per borrower, the program caps exposure at 5 loans or $2,500,000.
Title work scales with the line. A full title policy is required on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report. Hazard insurance covers both liens, with flood coverage where required.
Borrowers can be US citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Which Properties Qualify?
Eligible: single-family homes, PUDs, townhomes, two-to-four-unit properties, warrantable and non-warrantable condominiums, and lots up to 10 acres. Leverage tiers apply the same way across all of them.
Not eligible on this program: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, mixed-use property, a property listed for sale in the prior 2 months, and a property with a solar lien.
If your rental is on that list, a cash-out refinance may be the better route, since a different program can accept a wider property range. Each program has its own list.
HELOC, Purchase Loan or Cash-Out: Which Fits?
| Factor | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|
| First mortgage | You keep it | Replaced |
| Structure | Revolving line, one lien | One new loan |
| Cash delivery | At least 80% at closing | Lump sum |
| Best when | First mortgage is worth keeping | You need a larger lump sum or one loan |
A HELOC keeps your first mortgage in place and adds a lien. A cash-out replaces the first mortgage. Pick the HELOC when your existing first mortgage is one you want to keep and the equity room is there. Pick the cash-out when you need more than a second lien allows, or the rental falls into an excluded property type. You can compare more in Lendmire’s DSCR cash-out refinance guide.
For many first-time investors, the honest answer is that the line needs equity in a rental that has already seasoned. Lendmire’s piece on how much first-time investors can borrow against an investment property covers that path.
Risks and Who This Does Not Fit
Be honest with yourself on four points.
- More debt on the source rental. Rent used for lender review must cover the full limit even if undrawn, and you carry real interest on what you drew.
- Variable payments. The rate moves, and the repayment period raises the payment.
- Over-leverage. A line stacked on a first mortgage leaves a thin cushion if values drop. A declining-market flag can lower the ceiling.
- Personal liability. Members of an LLC sign as guarantors.
It does not fit an investor with no rental equity, a borrower below a 720 score who keeps a first mortgage, or anyone holding an excluded property type. It also does not fit someone who wants a standby line with a large unused limit, given the 80% closing draw.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.

LTV (loan-to-value): the loan balance divided by the property’s value, used when only one loan sits on the property.
DSCR (debt service coverage ratio): monthly rent divided by the qualifying payment.
Draw period: the stretch when you can borrow from the line and pay interest only on what you drew.
Second lien: a loan that sits behind your first mortgage in repayment priority.
Seasoning: the waiting period a rental needs after a purchase or refinance before it can back a new loan.
Frequently Asked Questions
Can I use a DSCR HELOC as the down payment on my next rental?
Yes, the cash can serve as a down payment, but the line itself never closes with the purchase. You draw against a rental you own, then use the money toward the next property, which needs its own financing. Expect the purchase lender to ask about the source of the funds.
What is the most I can borrow on a second lien?
The ceiling is $500,000, at up to 70% CLTV with a 720 score or better, subject to underwriting. Your actual number is value times 70%, minus the first mortgage, and rent coverage on the whole line must clear 1.10x. Lines start at $50,000.
Does the rent have to cover only the amount I draw?
No. The stress payment is calculated on the entire credit limit, drawn or not. At least 80% of the line (and never less than $50,000) is drawn at closing. If coverage falls short, a smaller line often fixes it.
Do I need a waiting period before I can open the line?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date).
